uau d7f6cb23de A/V sync: take audio filter buffers into account
Substract the delay caused by filter buffering when calculating
currently playing audio position. This matters for af_scaletempo which
buffers significant and varying amounts of data. For other current
filters the effect is normally insignificant.

Instead of the old time-based filter delay field (which was ignored)
this version stores the per-filter delay in units of bytes input read
without corresponding output. This allows the current scaletempo
behavior where other filters before and after it can see the same
nominal samplerate even though the real duration of the data varies;
in this case the other filters can not know the delay they're causing
in terms of real time.

uau 7deec05ea0 libaf: change filter input/output ratio calculations
Change the audio filters to use a double instead of rationals for the
ratio of output to input size. The rationals could overflow when
calculating the overall ratio of a filter chain and gave no real
advantage compared to doubles.

diego 7ee0eb4e19 Rename open to af_open so as not to conflict with a previous header definition.

reimar 6c232b95c4 We start with 0, so ch (channel number) == AF_NCH is invalid, too (not just >)

anders 6adaa78ee9 Changes includes:
- Improved runtime control system
- 3 New filter panning, compressor/limiter and a noise gate
  - The compressor/limiter and the noise gate are not yet finished
  - The panning filter does combined mixing and channel routing and
    can be used to down-mix from stereo to mono (for example)
- Improvements to volume and channel
  - volume now has a very good soft clipping using sin()
  - channel can handle generic routing of audio data
- Conversion of all filters to handle floating point data
- Cleanup of message printing
- Fix for the sig 11 bug reported by Denes

anders 66f4e56389 New features:
-- Support for runtime cpu detection
-- Stand alone compile of libaf
-- Unlimited number of channels (compiletime switch)
-- Sample format defined by bit-fields
-- New formats: float, A-Law and mu-law
-- Format conversion set in human readable format
   i.e. format=4:us_be to set 32 bit unsigned big endian output
-- Format reporting in human readable format
-- Volume control has only one parameter for setting the volume
   i.e. volume=-10.0:1:0:1 to set atenuation = -10dB
